python - 你能帮我用硒点击“去结帐”按钮吗

问题描述

我正在尝试做一个教程并在 python 中学习 Selenium，但是我似乎无法让 Selenium 使用 find_element_by_class 或 find_element_by_XPATH 来单击“添加到购物车”按钮。问题是检查该项目是否缺货，如果缺货则刷新网页并重新启动脚本。如果该商品有库存，则应单击“添加到购物车”

我在用：

Python v3.9

铬 v87

这是我正在练习的 URL（您可能需要在购物篮中添加一个测试项目才能看到按钮或运行脚本）：

这是我当前的点击代码：

# Wait 3 seconds

# Click "Add to Basket" or refresh page if out of stock

driver.execute_script("arguments[0].click();", button)

# Wait 3 seconds

# Click "Go to checkout"
button = driver.find_element_by_xpath("Go to Checkout")
driver.execute_script("arguments[0].click();", button)

解决方案

您无法单击的原因是又出现了一个隐藏Add to bastek按钮的弹出窗口。您需要先关闭该弹出窗口才能单击。

诱导WebDriverWait()等待element_to_be_clickable()跟随xpath选项

代码块：

driver.get("https://www.currys.co.uk/gbuk/tv-and-home-entertainment/televisions/televisions/samsung-ue75tu7020kxxu-75-smart-4k-ultra-hd-hdr-led-tv-10213562-pdt.html")
#Accept cookies
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.ID, "onetrust-accept-btn-handler"))).click()
try:
    #Handle pop up first
    WebDriverWait(driver,10).until(EC.element_to_be_clickable((By.ID,"gis-cta-awareness-close"))).click()
    #Click on Add to basket
    WebDriverWait(driver,10).until(EC.element_to_be_clickable((By.XPATH,"//div[@id='product-actions']//button[contains(.,'Add to basket')]"))).click()

except:
    print("element not found")
